ESP8266 Community Forum

I am working on a commercial design which is basically a WiFi based LED Light. I have ESP8266 WiFi module as my main controller. I have used simple HTTP Protocol to communicate the Light With Application. It Works smooth without any delay. The issue is, I want the group of 10-15 similar lights to glow or respond as one single light would do. I know this is the part of mobile app, but App can't handle 10-15 lights, send commands to these many lights at once and any delay would defeat the purpose. I know, a central hub would solve the problem, creating mesh network with others, but that's too much for my budget. I have seen some of the lights with this feature and can handle upto 8-9 Lights in a group.

How can I solve my problem? Do I need to change the Protocol to Websockets or mDNS? (Coz they have small overheads as compare to HTTP). Or Switch to Multicast Routing (mDNS).?

Yes, plain TCP sockets would be more efficient than HTTP requests.
(BTW, mDNS has nothing to do with Multicast routing, it is multicast Domain Name System)

The HTTP uses the TCP protocol by the way? You are talking about UDP?

Of course, I know that HTTP is also using TCP sockets ...
I've just said that Plain TCP sockets are much more efficient than HTTP Request.
